- I stream from a Macmini osX 10.5.6, Wired 100BT, using PS3MS official 1.10.5- Playing MPEG2, MKV without problems.

My problem is on MPEG4 files (H264) : the file on the local PS3 drive are working fine but from PS3MS it start playing and just after few seconds I have on the top right side of the PS3 the following message :"A network error has occurred"and straight away this one in the middle of the screen "This content can not be played 800288D8"

it only does it with MPEG4 files , If I go into the transcode folder then they work ok.The system is using Mencoder
